Re: Dubious diff using --diff-algorithm=histogram

[Alejandro Colomar <alx.manpages@xxxxxxxxx>]

Here's another example of a dubious diff using histogram:

@@ -50,8 +65,11 @@ .SH Examples
     nxt_unit_ctx_t   *ctx;
     nxt_unit_init_t  init;
 
-    bzero(&init, sizeof(nxt_unit_init_t));
+    if (argc == 3 && strcmp(argv[1], "-t") == 0) {
+        nthreads = atoi(argv[2]);
+    }
 
+    bzero(&init, sizeof(nxt_unit_init_t));
     init.callbacks.request_handler = &request_handler;
     init.callbacks.ready_handler = &ready_handler;
 


That call to bzero(3) is the only one in the entire file.
patience shows this instead:
